Structure comparison between ToCDS and EcCDS structures. (a) Superimposed structures of ToCDS (green) and EcCDS IscS (orange). The β-turn structure of ToCDS is labelled by a green arrow. The up-shifting C-terminal domain of IscS is shown by an orange arrow. (b) Superimposed structures of ToCDS (green) and EcCDS CsdA (purple). The bent helix α3 of CsdA is labelled by a purple arrow. (c) Superimposed structures of ToCDS (green) and EcCDS SufS (red).
